Planar microfluidic glass package for up to 1 ml/min

<p>With a tiny footprint of only 10x10 mm², Sensirion’s LPG10 liquid flow sensor series provides outstanding performance and speed in measuring liquid flow in a planar microfluidic glass substrate with down-mount fluidic ports for a highly compact integration into any fluidic manifold system. It is thus ideal for high-volume applications with strict space limitations. Two core technologies are combined at this point: microfluidics chips and digital microsensor chips. This unique approach enables measurement of liquid flow inside a cost-efficient planar glass substrate. The digital microsensor chip provides the full signal processing functionality for a fully calibrated, temperature compensated, and linearized digital output. The LPG10 series is a smart sensor solution offering flow rates from the low microliter per minute range up to 1 ml/min. Glass as the only wetted material ensures optimum compatibility with biological and pharmaceutical processes. Due to its small thermal mass, response times below 30 ms can be reached. This means that even highly dynamic changes in the flow rate (e.g. produced by pulsating micropumps) can be monitored with this sensor. One step further: the sensor’s signal can be used for a closed-loop control to reach continuous flows even with pulsating pump mechanisms. The small form factor literally allows direct and highly accurate measurements of the flow at any point of interest in a fluidic system. In addition, real time detection of failures such as clogging, air bubbles or leaks comes along for free.</p>
